Lockheed Martin [LMT] has received a $49.9 contract extension for production of the fire control Target Sight System (TSS) for the Marine Corps’ AH-1Z Cobra attack helicopter, the company said last week.

The Naval Surface Warfare Center awarded the initial contract in 2008 and a second production contract in June last year. Lockheed Martin delivered the first TSS in June 2009 and recently began delivery of low-rate initial production (LRIP) units.

Production is expected to run through 2018. TSS integrates state-of-the-art sensors to provide Cobra crews with imagery through a sensor suite. The suite includes a laser designator, color camera and a third-generation, mid-wave, forward looking infrared sensor with advanced image processing.

“TSS delivers precise targeting and accurate weapons delivery, while reducing operator workload,” Joseph Butera, senior program manager for Lockheed Martin’s Missiles and Fire Control sector, said.
